Abstract: Identification of starting and ending times of commercial breaks and commercials within those commercial breaks found in audiovisual content is disclosed. A solution to a “batch optimization” problem is used in which commercial locations within a set of audiovisual content are detected as a group by choosing a set of commercial locations which optimizes a cost function which can include considerations of, for example, 1) one or more cues, 2) relative locations of commercials within the audiovisual content, and/or 3) probability models based on statistics obtained regarding characteristics of typical commercial and commercial breaks. Optimization can be done over the total set of commercial location decisions, rather than on a per-commercial basis. Additionally, the cost function can be iteratively evaluated and many more types of cues and combinations of cues can be used in detection of commercials.

Abstract: The invention relates to a method and an apparatus for defining entry points for a data stream, in particular a stream of audiovisual information. Entry points in the stream are defined at a predetermined interval. This may be a time interval, a byte interval or any other interval. It is an object of the invention to provide an entry point table having a limited size. This object is achieved by increasing the interval between entry points if the table exceeds a predetermined size. This size may be defined in bytes, in the number of entry points or even in the number of sub-tables. After redefinition of the interval between entry points, entry points are redefined. The invention also relates to an apparatus for defining the entry points and to a record carrier with a data stream incorporating entry points defined by the method according to the invention.

Abstract: For a large capacity recording medium, a user interface having high flexibility and enriched representation is accomplished. A flag that represents whether a play item has a multiple angle structure of which the play item is reproduced with a plurality of angles is described. In addition, a flag that represents whether the beginning of each decode unit is an angle switchable point is described. In a seamless multiple angle structure, the current angle can be switched without need to increase the number of interleave units. In a nonseamless multiple angle structure, with the flag, in a predetermined region on the rear end side of each angle, the current angle is prohibited from being switched. Thus, when a play item exits from the multiple angle, discontinuity in the reproduction can be prevented. In addition, with a flag that represents whether a sub play item should be reproduced not in synchronization with a main path, the sub play item of only audio data can be used as a BGM.
